that's possibly true. it wasn't in all of the books, but at least in the one where i stopped reading. and it was insignificant because it served no purpose in the plot. what bothered me was not the reference to sex but the fact that it made no sense in the story and that it was treated as something as casual as a handshake and it simply felt like it was the authors personal fantasy.

and if i may say so, i suspect that in general reference to sex is so common that many of us don't notice. it doesn't bother me but i simply don't care for it when it's not a significant plot element. i grew up without any exposure to this kind of theme.
